high frequency

Frequency Range 10 MHz to 40 GHz

Bias Tees help add/remove DC current or voltage to/from RF circuits without impacting the RF signal. Typical applications include biasing active antennas, amplifiers and laser diodes, and for DC blocking or return in broadband microwave, RF and data communications. TTE’s BTHF Series is designed specifically for applications requiring high frequency performance. BTHF parts address frequencies from 10 MHz to 40 GHZ. They are provided with SMA female connectors or 2.92mm female connectors, depending on frequency range.  Please contact TTE for additional options.

* For RoHS compliant, insert “R” in place of asterisk.  Example: BTHCR-4G

TTE designates a component RoHS-compliant by adding “R” (RoHS) within the part number.  These RoHS components meet the ≤ 0.1% lead requirement.
